The figures below refer to a herd of water buffalo.

birth rate = 35
death rate = 7
immigration = 4
emigration = 17

what is this population growth?
population increases by 41
population decreases by 15
population increases by 15
population decreases by 24

Population Growth=

Birth Rate + Immigration - Death Rate - Emigration

35 + 4 - 7 - 17 = 15

The answer is the third option, population increases by 15

Hope this helps
